General Instruction of turbo-generator
Inquire NowDescription
The turbo-generator is a state-of-the-art energy conversion device designed for maximum efficiency and reliability. Its robust construction includes a welded steel sheet base seat, providing a lightweight yet strong frame. The generator features multiple air inlet and outlet areas to enhance performance. The rotor is crafted from high-quality alloy steel, with integral forging ensuring durability and strength. Precision processing with advanced machinery guarantees the optimal performance of the rotor winding.
Equipped with a stator coil built from multistrand, dacron glass silk-wrapped copper wires, the design incorporates a half-unit type and basket shape to enhance structural integrity. With an insulation grade of F, the stator coil is molded with mica tapes, ensuring resilience against sudden short-circuit conditions. The rotor, containing components such as the shaft, coil, center ring, and fan rings, utilizes cold-drawn flat copper wires that undergo oxygen-free annealing for enhanced electrical conductivity.
The turbo-generator is also equipped with high-strength aluminum alloy fans, ensuring efficient air movement. Additionally, the use of high-quality cold rolled silicon-steel sheets with low loss characteristics contributes to the overall performance of the generator.
